Krsna gives the power

When we become a devotee of Krsna, we become the instrument of Krsna and we see that Krsna begins to work through us and that we become empowered. One day Srila Prabhupada said, “My spiritual master made me into a diamond!” A diamond is completely transparent. The light goes through unobstructed in all directions. Thus a devotee becomes empowered to be an instrument of the Lord and then see what they can do. People say, “How can you do it?” Krsna gives the power, He makes it possible, so one who dedicates his life to Krsna becomes empowered by Krsna.
